Semantic Segmentation Example

Convert to VOC-like Dataset

# It generates:
#   - data_dataset_voc/JPEGImages
#   - data_dataset_voc/SegmentationClass
#   - data_dataset_voc/SegmentationClassVisualization

Note that the reason why the label file is mostly black is it contains only very low label values (ex. -1, 0, 4, 14).
